I am currently doing my PhD in sensor array processing and intend to test my algorithms on a microphone array system. Could you please direct me to some microphone array system (or some vendor) which I can use it to test my beamforming algorithms on?

Can you point me to some external and internal microphone arrays which will work with windows vista and are fully programmable through vista microsphone array APIs?

Hi Peter, thanks for your questions. You asked " are there ways of getting parts and building your own array-based stuff?". We're kindred spirits! Windows Vista does support USB based microphone arrays so you can plug in external devices of this type. If you have the right technical skills USB development kits are plentiful and we document USB Microphone Array requirements. Take a look at the article "How to build and use Microphone Arrays for Windows Vista" at http://www.microsoft.com/whdc/device/audio/MicArrays_guide.mspx. Also, you should review all the documents under "Microphone Arrays" found at http://www.microsoft.com/whdc/device/audio/default.mspx.

That said, purchasing a USB Microphone array solution off the shelf is more realistic and a huge time saver. That said, you would need to find a device that is Windows Vista compatible. If the device only works with its own set of drivers then it most likely does not expose its Microphone Array to Windows Vista in a compatible way.

Its great to see advances in Microphone technology, both my Sony camcorder and Canon camera sometimes pic up very low level noise when recording videos, bearable but annoying. Whats shocking is that these problems occur on most cameras to some extent ... I tried many brands/models before I picked up the Sony and Canon products which performed best. Some MiniDV camcorders I tried were really really bad.

Nice to see the design getting down to a single chip, anything that can reduce interference is desireable. Hopefully we will see these in Laptops soon, more and more people are using IM on laptops and Im sure that this advance will help bring this cool technology down in price and available to more people.

This is really interesting, Richard, but I still find myself wondering .. is this something we would see in external devices, too? Perhaps integrated into a webcam? I'd love to play around with it from a programming standpoint, but I don't see myself buying a laptop to do it, for one (and I expect adoption will be faster for software if there is external hardware, for the same reason).

I could also see this having HUGE potential for installations ... and the Vista features could make a Vista PC a useful coupling with this stuff. So I guess the next question is, consumer products aside, are there ways of getting parts and building your own array-based stuff?
